There were 4 of these flies on an elstar apple. Three were sitting motionless on the apple skin whilst one, which had a larger abdomen than the others, was busily feeding on the flesh exposed in a hole pecked by birds. Images 1 to 3 are of the feeding one. Image 4 is of motionless one with a thinner-abdomen.

Estimate 6-8mm long. In my garden. 5th Nov 2017, Flensburg, N.Germany.
Are they Anthomyiidae? Any guesses as to a Genus? Sex?

Thanks in advance

Despite of the 4 photos of this fly from many angles, I can't see the necessary characteristics to come to a possible genus or species.
It could be Hylemya or Pegomya or another genus.....
How many pd setae are there on the hindtibia, is the arista long haired or not, are there interfrontals present or not, a good view on the acrostichels....etc.
